Using public LDAP directories for attack preparation

["Per Thorsheim" <per () thorsheim net>]

I've seen a quite a few publicly available LDAP directories on the Internet
containing names, e-mail addresses and other employee information for a
company.

Besides the obvious possibility of harvesting working e-mail addresses for
spam purposes, has anyone successfully used such externally available
directories for doing targeted social engineering attacks as part of a
pentest?
